[NANOG] Downtown Los Angeles - Dark Fiber & DWDM Companies between buildings?

Morning, I am looking for dark fiber companies who operate out of Downtown Los Angeles that can offer us dark fiber service between some of the major buildings. Looking for any feedback, good or bad, from any providers people have worked with in the past -- happy to chat on and off list. We want to connect from One Wilshire (624 S Grand Ave) to the Aon Building (707 Wilshire Blvd) -- about 500 feet line of sight / 1 city block. Thank you! /adam -- Adam Brenner
